Description
Technical field
The invention belongs to power transformer technical fields, and in particular to a kind of three-phase has load oil tank of transformer, is suitable for
The three-phase of 110kV and above has load transformer.
Background technique
With the development of national economy and power industry, higher voltage grade, volume are smaller, non-oil ultra high vacuum system, lack oiling, intelligence
The development trend of transformer industry will be become by changing.Safe, high-quality, environmentally protective power transformer product will be in fierce market competition
In have the advantage status, while each single item progress of such power transformer product is to ensureing that electric power netting safe running is of great significance.
Conventional oil tank of transformer mostly uses slab construction to design at present, and it is not big enough, transformer oil that there are fuel tank intensity
The technical problems such as dosage is more, fuel tank heat dissipation area is less than normal, transportation clearance is excessive.
Summary of the invention
The main purpose of the present invention is to provide a kind of three-phases load oil tank of transformer, can effectively solve in background technique
The problem of.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of three-phase has load oil tank of transformer, and the arc section tank wall including front and back side, the inside of fuel tank is along its length
Be arranged successively and be provided with oil tank in No.1, No. two upper oil tanks and No. three upper oil tanks, and the inside of fuel tank along its length
Direction, which is arranged successively, is provided with No.1 lower oil tank, No. two lower oil tanks, No. three lower oil tanks, the arc section tank wall and three
The corresponding position of upper oil tank is respectively arranged with an evagination circular arc, and the two sides of three evagination circular arcs are disposed with No.1 slot type and add
Qiang Tie, No. two slot types reinforce iron, No. three slot types reinforce iron and No. four slot types reinforce iron；The fixed peace of the inner wall of the arc section tank wall
Equipped with winding inside lead and three three-phases, and lead is located at the top of winding inside three-phase.
Preferably, the outer surface that the No.1 slot type reinforces that iron and No. four slot types reinforce iron offers oil filler point, oiling
Hole reinforces iron through No.1 slot type and No. four slot types are reinforced iron and connect with arc section tank wall.
Preferably, oil tank, No. two upper oil tanks and No. three upper inline installations of oil tank in the No.1, and one
The capacity of oil tank, No. two upper oil tanks and No. three upper oil tanks is identical on number.
Preferably, the No.1 lower oil tank, No. two lower oil tanks and No. three inline installations of lower oil tank.
Preferably, winding is set in concentric circles inside the three evagination circular arcs with three-phase of the outer surface of the arc section tank wall
It sets, and lead is connect with winding inside three-phase.
Preferably, the No.1 slot type reinforces iron, No. two slot types reinforce iron, No. three slot types reinforce iron and No. four slot types are reinforced
Iron passes through welding and is fixedly connected with arc section tank wall.
Compared with prior art, the invention has the following beneficial effects: the three-phases load oil tank of transformer, passes through setting
Oil tank, No. two upper oil tanks and No. three upper oil tanks on arc section tank wall, No.1:
1 arc section and coil group are arranged in concentric circles, can effectively reduce leakage magnetic flux and penetrate tank wall, form overheat and add
Loss, to improve transformer station high-voltage side bus economy.
The structure of 2 arc sections uses a bent into shape, and intensity is better than slab construction, and that replace former flat areas to add slot
Formula reinforces iron construction (arc section tank wall part is not provided with reinforcing iron), only increases in the two sides of arc section tank wall and middle planar region
Add slot type to reinforce iron, saves economic cost.
3 arc sections effectively reduce the internal volume of fuel tank body, and the transformer oil of consumption is reduced, meet transformer non-oil ultra high vacuum system,
The development trend of few oiling.
4 oil tank of transformer are the important media of transformer heat dissipation, and heat is disseminated to air by convection current and radiation mode
In the middle, and arc section tank wall increases the contact area with air compared with plate tank wall, greatly improves the heat dissipation of transformer itself
Ability is conducive to the operation of transformer long-term safety.
5 can effectively reduce transformer transporting width using arc section tank wall fuel tank, especially for the biggish change of capacity
When depressor transportation clearance is severely limited, the present invention will be the effective way solved the problems, such as, can reduce transportation cost.
Entire three-phase has load transformer oil tank structure simple, and easy to operate, the effect used is more preferable relative to traditional approach.
